Photothermal conversion regenerated desiccant sheet, desiccant element and desiccant rotor using the sheet, and air conditioning system using the element or rotor

摘要

Conventional desiccant air conditioning systems that use light energy such as sunlight have problems in efficiency and regeneration temperature, and are not sufficiently satisfactory in terms of performance. An object of the present invention is to provide a desiccant sheet that can efficiently use heat energy obtained from light energy such as sunlight and can absorb and release moisture, and further, a desiccant element using the sheet, and It is an object of the present invention to provide a desiccant rotor and a desiccant air conditioning system using such an element or rotor. The object of the present invention is achieved by including a moisture absorbing / releasing material and a photothermal conversion material as essential components in a desiccant sheet. Here, it is preferable that the moisture absorbing / releasing material and the photothermal conversion material are in direct contact with each other at least in part or in close proximity via a resin.
